feat v1.23.1: openings — hover outline, drag along walls, double-click properties

- Hover: an accent outline hugs the opening's wall strip + grab cursor.
- Drag (view mode): re-snaps continuously to the nearest derived wall; snapToWall now
  normalizes the angle to [-90,90) — neighbouring rooms yield the same wall in opposite
  directions, which used to flip the hinge while dragging across segment boundaries.
  setPointerCapture wrapped in try/catch (an inactive pointerId must not kill the drag).
- Click still opens the status card (via a 250ms timer); double click opens the
  properties dialog from view mode. Hit zone is now a slightly thicker strip along the
  wall instead of the whole swing square (fewer accidental hovers). +1 test (77).
Verified live: drag moved a test door exactly along a vertical wall (angle 90 -> -90),
click/dblclick/markup-tool paths all работают; the user's 12 real openings untouched.

 # Changelog
 
+## v1.23.1 — 2026-07-17 (openings: hover, drag along walls, double-click properties)
+- **Hover affordance**: an accent outline hugs the opening's wall strip on hover, with a
+  grab cursor — placed openings now look grabbable.
+- **Drag along walls** (view mode): an opening re-snaps continuously to the nearest derived
+  wall while dragged; too far from any wall → it stays put. `snapToWall` now normalizes the
+  angle to [-90, 90) — two rooms share a wall with OPPOSITE edge directions, and without this
+  a drag across segment boundaries flipped the hinge side back and forth. Saved on release.
+- **Click / double click**: a single click still opens the status card (now via a 250 ms
+  timer); a **double click opens the properties dialog** right from view mode. The markup
+  "Opening" tool behaves as before. Hit zone made slightly thicker and is now a strip along
+  the wall (previously it covered the whole swing square, causing accidental hovers).
+- (+1 test: 76 → 77.)

 ## v1.23.0 — 2026-07-17 (doors & windows with live open/lock state)
 Visual language after easy-floorplan (MIT); the placement model is ours.
 - **New markup tool "Opening"**: click next to a wall → the opening snaps onto the nearest

 | CI | `.github/workflows/validate.yml` (hacs + hassfest + frontend + backend) — **fully green** since v1.11.1; `release.yml` auto-attaches the card bundle (needs `permissions: contents: write`, fixed) |

Lesson: #8995 was auto-closed by hacs-bot — the PR body MUST be their exact template with every checkbox ticked and all 3 links (release, HACS action run, hassfest run); a custom body gets closed without discussion |
 | Brands | Ships **inside the integration**: `custom_components/houseplan/brand/{icon,icon@2x,logo,logo@2x}.png` (HA ≥2026.3 local-brands mechanism). home-assistant/brands PR #10700 was auto-closed — that repo no longer accepts custom integrations |
